SPECIFICATION forming part of Letters Patent No. 476,366, dated J une'7, 1892. Application tiled October 22, 1889. Serial No. 327,816. (Nomodel.)

To all whom it may concern:

Be it known that I, ROBERT S. COX, a citizen of the United States,residing at Terre Haute, in the county of Vigo and State of Indiana,have invented certain new and useful Improvements in Dump-Cars, ot whichthe following is a specification.

This invention relates to dump-cars; and it consists in theconstruction, combination, and arrangement of parts, as hereinaftershown and described, and specifically pointed out in the claims.

In the drawings, Figure l is a semi-sectional side elevation, Fig. 2 isa plan view, and Fig. 3 is a cross-sectional view on the line fr a ofFig. l., of one ot my dump-cars complete. Fig. i is a view similar toFig. 3, showing a slight modification in the construction. y

A represents the floor-frame, A2 the side fram es, and A3 the trucks, ofa car, these parts being ofthe ordinary construction, except that thefloor is provided with openings d along the sides between the trucks,these openings being covered by.downwardlyopening doors or drops B.These doors B are each hinged by one edge to the licor-frame, as shown,and supported by chains D by their free edges, the chains passing upwardover rods or windlasses E to arms E2 or to other devices whereby thedoors may be elevated or allowed to be depressed. The openings a willgenerally be arranged between the trucks, so that the material beingdischarged from the car will not fall upon the axles or truck-frames.

In Figs. l, 2, and 3 the interior of the carbody is formed hopper-shapedby inclined sections F, which cause all the contents to run down throughthe openings a when the doors B are opened, while in Fig. 4: theinterior is without these inclined sections.

I.Vhile the presence of the inclined sections renders the discharge ofthe contents of the car more convenient, I do not `wish to be limited totheir use, as the car is operative without them.

The openings d may be of any required size and may be of any desirednumber, but will occupy the same relative position with relation to thebottom and sides of the car-viz., along the sid es-as the location ofthese openings, and the manner in which they are employed is one of theprincipal features ot` my invention.

This class of du mp-cars are employed more particularly inrailroad-graditi g work in transporting earth and similar material andin discharging it quickly at whatever point desired.

By arranging the discharge-openings a in the bottom along the sides I amenabled to discharge the material from the cars close to the .outside ofthe track when the doors B are hung by their inner edges, as in Fig. 3,orbetween the rails when the doors are hung by their outer edges, as inFig. et.

In grading railroads the earth is required to be discharged as close tothe rails as possible, either inside or outside, to produce the bestresults and avoid the necessity for rehandling by shoveling orotherwise. In completin g fills around trestle-work and other similarlocations this ability to discharge the earth close to the track orbetween the rails is of especial advantage, and the extreme simplicityof the construction of my car and the method oi' accomplishing thisresult render it of great importance.

The doors B by the method of supporting them serve as chutes to theearth when being discharged, so that it is conducted from the car in anydesired quantity or with any desired degree of force.

I have shown in Figs. l, 2, and L and the left of Fig. 3 the doors B,adapted to be actuated by chains D, connecting them to horizontal shaftE", the revolution of the rods winding the chains upon the rods asdrums, while on the right of Fig. 3 I have shown an arm E2, attached tothe shaft E', and with a chain D connecting its outer end with the doorsB, the revolution of the shaft E causing the outer ends of the arms torise and fall and thus open or close the door B; but I do not wish to belimited to any specific method of operating the doors, as Iam aware thatthey may be operated by other suitable devices than those shown.

Having thus described my invention, what I claim as new isl. In a dump-car, the combination, with the frame and inclined bottom, ofdownwardlyopening doors hinged to the bottom, a longitudinally-arran gedshaft j ournaled in the ends IOO ot the car above the doors, and chainsdirectiy connecting the shaft and free edges of the doors, substantiallyas and for the purposes described.

2. In a dump-car, the combination, with the frame and inclined bottom,of downwardlyopening doors hinged at their inner edges to said bottom, alongitndinally-arranged shaft journaled in the ends of the car invertical alignment with the free edges of the doors, and chains securedto said free ends, having their upper ends wound around and secured tothe shaft, whereby upon the unwinding of the chain the doors arelowered, substantially as and for the purposes described.

3. In a dump-car, the combination, with the frame and inclined bottom,of hinged doors forming chutes hinged at their inner edges to ROBERT S.COX.
